| (54) | Shift controlling apparatus for continuously variable transmission |
| (57) A shift controlling apparatus for a continuously variable transmission changing of
an input side rotational element driven by an engine via a power transmitting element
to an output side rotational element, has, a rapid acceleration determination unit
for determining whether or not a rapid acceleration demanding condition according
to the depressed amount of an accelerator pedal, basic shift mode setting unit for
setting a rotating speed of the input side rotational element based on a basic shift
mode according to operating conditions such as throttle opening, vehicle speed and
engine speed, accelerating shift mode setting unit for increasing the vehicle speed
based on an accelerating shift mode correspondingly to an increase in engine speed,
and a control unit for switching from the basic shift mode to the accelerating shift
mode when the rapid acceleration determination unit determines that a rapid acceleration
demanding condition occurs. |
